  • image of flyguye SSL setup for email server & webmail $110.00 USD

    “Right from the start, the freelancer was proactive & his level of English was excellent. This made communicating what i wanted easier & what he conveyed clear. His professionalism is a breath of fresh air & is most definitely welcome here on freelancer where we sometimes end up with a rotten apple that leaves a sour taste in our mouths. He was quick off the mark & pointed out several errors within my server setup as well as scripting, issues. There is no doubt that anyone who hires him will be more than satisfied with his work. Well done Szymon! Would definitely hire again in a heartbeat. Cheers!”
